prompt | string, required | — | Up to 6,000 characters. |
aspect_ratio | 21:9 / 16:9 / 4:3 / 1:1 / 3:4 / 9:16 | 16:9 | Output frame shape. |
resolution | 540p / 720p / 1080p | 720p | Sets the per-second rate. |
duration | 5 / 10 | 5 | Output length in seconds. |
loop | boolean | false | Make the clip loop. |

Hosted files
Pass a publicly accessible file URL in the model’s image, video or audio field. Supported formats and limits are shown beside each Playground input.
Uploading images
Use the upload or replace control on supported image fields in the Playground. Video URL fields accept a hosted driving video; they do not imply video-upload support.
